    This was one of the best power banks I have.. Long lasting, I already charged both my phone and my husband but the indication light is still on 3 out of 4 ( 3 means 75% while 4 means its on 100%).. With said probably I could charge a lot more before the I could plug the powerbank to charge it back.. A definite must have especially for long trips.. The purchase was super worth it..
